I can confirm I've tried it on a machine. The performance impact was
substantial (at least if I allowed it to go to its lowest speed); the
power consumption difference was immeasurable[0].
Have you actually measured the power savings?
[0] Immeasurable as in the measurement equipment (an UPS with load
indication, in this case) could not notice any difference. The same UPS
does notice a substantial difference with K8 chips.
